What is correct about the process of dissolution?

Dissolution is driven by how well the solute and solvent interact with each other. The extent to which a substance dissolves depends on the strength and nature of those interactions: the solvent must be able to stabilize the solute particles once they leave the solid lattice, which happens only if the solvent–solute interactions are favorable compared to the forces holding the solute together. Because this compatibility between the specific solvent and solute is what governs solubility, it’s the most general and reliable factor. Temperature can influence how much dissolves in many cases, and dissolution can often be reversed by removing the solvent, but these effects are system-specific and not universal. The fundamental determinant remains how the solvent and solute interact with each other.
